Abstract (en)
[origin: WO2015169497A1] A method for diagnosis of a state in a vehicle (2), which has a CAN communication bus (4) to which electronic control units (5, 6, 7) of the vehicle are connected, has the following steps: provision of an idle state of the vehicle (2), in which at least some of the electronic control units (5, 6, 7) are set up not to send a CAN message via the CAN communication bus (4) during correct operation, coupling of a diagnosis tester (10) to at least one diagnosis port (3) of the vehicle (2), which can be coupled to the CAN communication bus (4), monitoring of the CAN communication bus (4) by the diagnosis tester (10) for sent CAN messages (21 -2n) following entry into the idle state, detection of a CAN message (21) that is sent on the CAN communication bus (4) following entry into the idle state, and association of the detected CAN message (21) with an electronic control unit (6) sending the CAN message by the diagnosis tester (10), provision of information (14) concerning a temporal occurrence of the detected CAN message (21) in a series of CAN messages (21-2n) occurring following entry into the idle state on the CAN communication bus (4) by the diagnosis tester (10), and provision of information (31, 41) for the identification of the electronic control unit (6) sending the detected CAN message (21) by the diagnosis tester (10).
